Penthode, Well it looks like you nailed it. I pulled the back off, stamped on the cabinet is 50-10-05. Also, I wondered why it was so light. I could actually pick it up by myself without breaking my back. No transformer, lots of electrolytic cans, large power resistor and 3 stages of selenium diodes. The chassis is nicely spread out and connected by plugs and sockets. Also, nice and clean with no rust. There is no cage around the flyback and H.V. circuit, which is about an inch away from the speaker. The 10BP4 picture tube tests good. Looks like 26 tubes total including the picture tube. 3 6J6's for the tuner. Sadly,... no photo's until my wife tells me where she hid the camera.

So you acquired the set? If so great!
Please keep us posted on this. It is an I interesting set. |

So, how different is this model than say the European Philips models? I would have figured they would have taken an existing chassis and modified it to suit the power and receiving needs for Canada. Or, was it more economical to design something from scratch?

Cambridge, huh?
Long shot here but are there any marks indicating if/where the last time this set was serviced? |

They probably based the set on an existing north american design rather than grabbing something from europe and re-engineering it to handle NTSC.

Looking underneath the chassis shows almost no servicing in the past. The cabinet was designed so the chassis could be slid out the back without removing the knobs. The front bezel is a "split" design to go in behind the knobs once the chassis is installed. I tried to remove the inner knobs with the chassis still in the cabinet. There are actually set screws installed on the inner knobs. So,.. until you remove the bezel, remove the chassis and slide the outer knobs back toward the chassis you would never see the grub screws. I thought, oh great more seized knobs ! Here are some photo's.

When you get a schematic, please post it. This is one amazing set.
Looking closely at the photos, it appears that there is a soldered connection on the top of all of the electrolytic cans. Is this the negative connection for the capacitors inside the can? Last edited by Tom9589; 10-11-2018 at 11:50 AM. |

I was provided the full service information volume for all early Canadian Philips/ Rogers televisions by Mr Earl Ryder of Ryders TV service in Georgetown Ontario in 1971. I still have it in a box in storage. I will look for it but it will be a few months before I may find it.
In the meantime, the Toronto Reference Library located just north of Bloor Street on Yonge used to keep a copy of it. |

I wouldn't count on any library retaining such docs indefinitely. My regional library used to have a complete set of Riders TV manuals, as well as a subscription to Sams allowing me to download any Sams manual free.
They discontinued the Sams subscription last year because the demand was insufficient to justify the expense. A couple of months ago I went there to photocopy something from Riders and they told me they had disposed of that whole set, too. To quote the librarian, "You might be the only person who looked at that set in the last decade." In a library, space costs money. Phil Nelson Phil's Old Radios https://antiqueradio.org/index.html |

Seeing selenium rectifiers and a rather small transformer (probably just for tube heaters) I'd agree.

I recall the filaments were series strung negating the need even for a filament transformer. If the horizontal output is a 19BG6, that would clinch it.

I was actually quite lucky the other day. I was searching E-Bay and came across an original Rogers-Majestic / Philips service manual #1 for years 1948-1952. The seller said it has the DV1050 in it. Hopefully it should arrive by the end of the week. Also, the price was right.

The manual you found is exactly the same as the one given to me in 1971!
